PROBLEM TO BE SOLVED: To improve noise at the time of travelling using a tire worn out by suppressing uneven wear of the tire.SOLUTION: The pneumatic tire comprises: a first circumferential groove 31; a land part 36 which is provided outside in a tire width direction of the first circumferential groove, continues across a whole tire circumference and continues from the first circumferential groove to a tire grounding end toward outside in the tire width direction; a first inclined groove 32 which approaches in a first direction of the tire circumference direction and extends while inclining to outside in the tire width direction, with a position separating outward in the tire width direction from the first circumferential groove as a starting end; a first rug groove 33 which extends from an end part outside in the tire width direction of the first inclined groove to the grounding end; and a second inclined groove 34 which extends in a second direction opposite to the first direction from a connection part between the first inclined groove and the first rug groove. A sharrow bottom raising part 40 with a shallow groove depth is provided in the connection part so as to reduce heel-and-toe wear in the connection part in which rigidity of the land part deteriorates.SELECTED DRAWING: Figure 2

    【課題】タイヤの偏摩耗を抑制することで、摩耗後のタイヤを使用して走行する時の騒音を改善する。【解決手段】第1周方向溝31と、第1周方向溝のタイヤ幅方向外側に設けられ、タイヤ全周にわたって連続するとともに、前記第1周方向溝からタイヤ幅方向外側にタイヤ接地端まで連続する陸部36と、第1周方向溝からタイヤ幅方向外側に離間した位置を開始端とし、タイヤ周方向の第1の方向に向かうとともに、タイヤ幅方向外側に傾斜して延びる第1傾斜溝32と、第1傾斜溝のタイヤ幅方向外側端部から接地端まで延びる第1ラグ溝33と、第1傾斜溝と第1ラグ溝との接続部から第1の方向とは反対の第2の方向に延びる第2傾斜溝34とを備えるタイヤである。溝深さが浅い底上げ部40を接続部に設けることで、陸部の剛性が低下する接続部におけるヒールアンドトウ摩耗を低減する。【選択図】図2
